Anyone who might be interested in knowing a bit more about the PSP Go can read this thread: http://www.vgchartz.com/forum/thread.php?id=76872
Personally, I'm getting a DSi today (a gift from my mom), and I will be getting a PSP Go around its launch. The PSP Go is more my kind of machine, but the DSi still has enough games I want (most notably, Scribblenauts!).
